The present work explores the possibilities of developing finger millet starch (FMS) films with sorbitol (DS) at various concentrations. Therefore, starch is isolated from three diverse underutilized Indian finger millet varieties (VL‐149, VL‐371, and VL‐376). The results reveal that amylose content, moisture content, and ash content of FMS are observed in the range of 31.12 ± 0.37–33.87 ± 0.64%, 8.47 ± 0.75–9.87 ± 0.37%, and 0.33 ± 0.18–0.78 ± 0.91%, respectively. In addition, the solubility and swelling index of the FMS is found to be in the range of 1.5 ± 0.34–1.7 ± 0.11% and 9.98 ± 0.31–11.25 ± 0.64% at 60 °C. This work investigates the effects of varying concentrations (20%, 30%, 40%, and 50%) of sorbitol (DS) as a plasticizer on the FMS film's main functional properties, thermal, and structural. The results present that elongation at break‐point is increased while film density, swelling index, water vapor permeability, tensile strength, and solubility are reduced upon the addition of DS. Scanning electron microscope images show that the FMS film surfaces with DS are more homogeneous and continuous without air bubbles than those without DS. Thermal gravimetric analysis and differential scanning calorimetry results indicate that the thermal stability of the FMS film improves with DS.

Moth bean starch (MS), gelatin (GA), and Murraya koenigii leaves extract (ME) are blended at different compositions to prepare film and coating according to casting and dipping approaches. Different MS, GA, and ME compositions were used to synthesize films and coating. The film compositions (MS : GA: ME: 60 : 20 : 20 and MS : GA: ME:20 : 60 : 20) were represented in terms of F3 and F4, respectively. The results showed that F3 exhibited better physicochemical properties than other films. In addition, SEM images showed that all components of the films were uniformly mixed and formed smooth surface morphology without cracks and bubbles. FTIR results indicate that ME in the films induces interactions between the film components, causing an improvement in compactness. Moreover, an optimized film-forming solution was tested as a coating. Parameters such as skin tightness, weight loss, pH, titratable acidity, and sensory analysis were considered to check the quality of coated Solanum melongena during storage. The results show that the formulation effectively maintains the quality parameters during storage. Furthermore, it also notices that coating extends the shelf life of Solanum melongena by one week.

“…El almidón es uno de los polisacáridos más abundantes en la naturaleza, de bajo costo, que representa la principal reserva energética de las plantas y que constituye más del 60% de las semillas de cereales (Jiménez et al, 2012); se sintetiza en los amiloplastos de las plantas y se almacena principalmente en semillas (maíz, trigo, arroz), raíces o tubérculos, estos últimos con el mayor contenido de almidón (Gautam et al, 2021).…”

“…Mientras que la amilosa, forma complejos helicoidales con compuestos aromáticos, emulsionantes y lípidos, llamados complejos de amilosa tipo V (Wang et al, 2019). Aunque la amilosa permite la formación de películas fuertes, isotrópicas, inodoras, insípidas e incoloras (Jiménez et al, 2012), se ha observado que combinar dos o más biopolímeros permite conseguir materiales con propiedades mecánicas, que pueden ser una alternativa efectiva para la sustitución de empaques plásticos (Gautam et al, 2021;Gómez-Aldapa et al, 2020a).…”

“…De este último, se han elaborado películas, sin embargo, sus propiedades mecánicas aun no pueden competir con las que presentan las películas sintéticas, lo que dificulta empaquetar productos húmedos; en consecuencia, se ha buscado innovar la conjugación con otros biopolímeros, con la finalidad de mejorar su desempeño mecánico y de barrera (Gautam et al, 2021;Khalil et al, 2018).…”

El incremento poblacional de los próximos años, causará el aumento de empaques plásticos no biodegradables destinados a la protección de alimentos, lo que dificultará garantizar la seguridad alimentaria, sin afectar el ambiente. Dentro de los bioplásticos, el uso de películas hechas a partir de almidón, tiene potencial para sustituir gradualmente a los empaques tradicionales; sin embargo, su uso en los alimentos es limitado aún debido a sus propiedades funcionales débiles. A nivel industrial, se ha buscado generar películas de almidón a partir de los residuos de biomasa agrícola, con el fin de disminuir el impacto ambiental, generando una economía circular. Por ello, esta revisión recopila las investigaciones de los últimos cinco años que buscan mejorar las propiedades funcionales de las películas de almidón de papa, para obtener empaques capaces de extender la vida de anaquel de los alimentos y garanticen la seguridad alimentaria con precursores sostenibles a través de una economía circular.
